WOODEN PIPE.

SPECIFICATION forming part of Letters Patent No. 268,024, dated November28, 1882.

Application filed August 14, 1882.

To all whom it may concern Be it known that we, LUMAN FORD J OHN- sortand IRA EARLL WILLIAMS, citizens of the United States, residing inPalmyra, in the county of Wayne and State of New York, have inventedcertain new and useful Improvements in Wooden Pipe, of which thefollowing is a specification. y

The object of this invention is to produce a cheap, light, strong, anddurable pipe for conducting water through towns or cities, or forirrigation, or any other purpose to which it may be adapted, all ofwhich will be more clearly hereinafter shown by reference to theaccompanying drawings, in which- 7 Figure 1 is a side elevation ofajoint of pipe; Fig. 2, an end view; and Fig.3 is a vertical longitudinalsection through line or as, Fig. 2.

The pipe is made of wood or other suitable material, wood beingpreferable as the cheap est, lightest, and best. It is made in sectionsor strips 11, (see Fig. 2,) which are put together and held securely byiron or other suitable bands, b. To insure sufi'icient strength toresist internal pressure, it is bound by wire bandsc, arranged intheform ofa spiral around it, (see Fig. 1,) the end of the wire beingsecured by screws or other similar means, d. The binding-wire 0 may beeither flat or round, or any other form; but flatbands are best wheregreat strength isrequired. Besides, it does not sink into the Wood sodeeply as round wire. The size and quantity of this wire will bedetermined by the size of the pipe and the pressure it will have towithstand. One end ofeach joint of pipe is provided with asmallerportion or neck, 6, adapted to slip into and fit closely theenlarged inside portion, f, of another joint,

(-N 0 model.)

the joints being made water-tight where the ends of the pipe are puttogether in any wellknown way. In using this pipe in salt water, orwhere iron will not stand well, brass or copper may be substituted forthe bands or wire. The joints of pipe may be made of any desired length,and to protect them on the outside, when necessary, they are immersed inboiling coal-tar or other suitable material for a sufficient length oftime to insure its penetrating to a short distance below the surface oras far as may be desired. In doing this the ends should be stepped upwhen the inside is not intended to be coated with the tar.

By making the pipe of several narrow strips or staves a great saving ofstock is effected and a much larger pipe can be made than when made intwo pieces, as heretofore.

The object in coating only the outside with coal-tar or its equivalentis to prevent it from affectin g the water, and also to protectit fromdecay. The inside of the pipe, so long as it is filled with water, iswell protected from decay.

We do not claim broadly a wooden pipe constructed of two semicircularpieces and bound together with bands and wire; but

What we do claim as our invention is- A wooden pipe consisting of aseries of narrow strips or stares, a, secured together by bands b c, andimmersed in boiling coal-tar, so as to penetrate and coat the outsidesurface, substantially as and for the purposes specified.
